Texas Joint Fill Floor Repair

SealBoss JointMaster Pump Rushed to El Paso

Another High School Floor Repaired & Concrete Joints Filled in Texas

A SealBoss Technical Rep drove down to El Paso, TX in timely support of local contractor who upgraded from an old outdated pump with polyethylene tanks, that was difficult to use and clean, to the stainless steel tank equipped new Jointmaster Pro 2 G3i polymer joint filler pump.

How to Operate and Clean a Joint Filler Pump

“On-site training consists of an overview of the machine and it’s features. This is followed by hands on training with actual dispensing of material into the joints until the applicator has gotten comfortable with the application techniques and nuances of the material used. Finally we focus on the correct cleaning procedure of the equipment.

We won’t leave a jobsite till I know everyone is comfortable with the systems and can reteach the next person in line.

Instead of breaking out the tools and hoping you can find parts for your old bulk dispensing pump, maybe it is time to upgrade to the SealBoss Jointmaster 2 and schedule your on-site training to get you comfortable with your new machine.

With a knowledgeable technical support team, we are here to help with any questions you may have.”

Hollow Core Concrete Slab Water Leak Repair

Hollow Core Concrete Slab Injection

What is a Hollow Core Slab ?

A hollow core concrete slab, also known as a hollow core slab, is a precast slab of prestressed concrete, typically used in the construction of floors in multi-story buildings and parking structures

Parking Garage Repair with SealBoss 1510 Foam Injection

The Problem

The client was experiencing water intrusion through hollow core concrete slabs and along exterior wall and sill plate cold joints in below parking garage causing water to drip onto cars and creating unsightly watermarks on the walls.

A waterproofing contractor was asked to seal the cold joints and cracks in the affected hollow core concrete slabs, and to determine and stop the source of leakage.

The Solution

To address the issue of the leaking hollow core slab, the contractor reached out to the SealBoss Regional Sales Manager to advise on the injection of the hollow core slab.

With a quick walk around the exterior, it was made clear that there were drainage issues where the downspouts fed the run-off onto a grassy area with no sloping to direct the water away from the building.

Once the source of the leak had been determined, a two-step injection strategy was adopted as the best solution. The initial injection was to inject cracks in the hollow core slab where water was leaking out and dripping onto vehicles. The subsequent injection would be to seal off the end caps of the hollow core cells where the leak originated.

Once the contractor began to drill holes for the injection packers, water poured out and it was obvious that the hollow core was completely filled with water. After the water was drained the crack was injected and sealed.

To verify that water had not traveled between cells, weep holes were drilled into the adjacent cells. Water was found to have also filled another cell of the hollow core and had to be drained.

Using a borescope, it was confirmed that there was water intrusion where the hollow core had been capped off with a plastic cap (see video below).

The weep holes were left open to prove that the leak had subsided.

The client was advised to add drainage boxes to help direct flow away from the building in areas where water pooled and to notify contractor of any new leaks this upcoming spring when the ground will thaw.

SealBoss 1510 NSF/ANSI 61 Water Stop Foam was injected into the exterior cold joint along the areas where water intrusion was visible from efflorescence or rust stains. All visible leaks were addressed using the 1, 2, 3, 45 Degree method via injection packers that were placed roughly 12” from the joint where ½” holes were drilled at a 45-degree angle back into the joint. 1510 was injected until positive refusal of the hydro-active resin was visible along the cold joint.

All affected cells of the hollow core concrete slabs were injected approximately 6” from the end cap and sealed off using SealBoss 1510 NSF/ANSI 61 Water Stop Injection Foam System.

Blanket Injection – Horizontal Waterproofing

Blanket Injection

Horizontal Waterproofing Injection Technique

What is Blanket Injection?

The process of Blanket Injection or Horizontal Curtain Injection involves injecting a water activated, single component polyurethane foam or gel resin into the space between a slab and the supporting soil substrate for the purpose of providing a waterproofing barrier. The objective is to prevent erosion and water seepage from below the slab through any cracks and joints.

Blanket Injection and Curtain Injection are considered primarily waterproofing injection methods and should be performed using chemical grout resins with excellent penetration and moderate gel time properties. With accelerator controlled systems, gel times are adjustable to suit the individual conditions on the jobsite.

If left untreated, cracks and joints in concrete slabs permit water migration into the structure driven by hydrostatic pressure — leading to rebar corrosion, mold, and further destruction of other infrastructure, including damages to walls, doors, furniture, equipment and more.

Void Fill and Blanket Injection with SealBoss 1510 Polyurethane Chemical Grout

Scope

A mixed-use, commercial and agricultural building in Oklahoma had a water pipe burst under substantial hydrostatic pressure, causing significant erosion under the concrete floor with the potential for subsequent water ingress through cracks and joints throughout the whole mixed-use building.

Solution

The proposed solution was to fill the voids and to create a waterproof barrier und the slab using the Blanket Injection Method.

Filling of the voids and creating waterproof barrier underneath the slab was achieved by using an expandable, water-activated, single component hydrophobic chemical injection grout with excellent void filling, penetration, and waterproofing properties.

The gel time needed to be adjustable for shorter and longer gel times. The product had to react on contact with moisture, and the expansion pressure had to be controllable, to avoid any lifting of the slab.

SealBoss 1510 with SealBoss 15X Accelerator were the products of choice.

Overview of Repair

Injection packers were set in a grid pattern, roughly a three foot on center grid with an expected travel of one and a half feet in all directions from the point of injection. The expected travel would be accomplished by varying the SealBoss 15x accelerator/catalyst percentage between 5% and 20% by volume based on real time behavior of substrate.

Monitoring

Since this application was performed during a contractor training, travel of foam was monitored in three separate ways to visualize the effectiveness of the repair.

Firstly, the removal of an adjacent packer creates a control hole for the successful spread of injection grout, and an immediate path of least resistance, allowing for some displaced substrate and water to escape from the open hole rather than building up and creating blockages.

In addition, a Borescope and a Thermo-Imaging Camera were used to visually enhance the training. However, neither a borescope, nor a thermographic camera are essential tools for successful blanket and curtain injection procedures.

The borescope was used to get a visual of the void prior to injection and to observe the travel of foam during the injection process. The thermo-imaging camera was utilized during the injection process to visualize the spread of the expanding exothermic injection grout.

Find more information on the use of thermography for injection process monitoring here.

Injection Process

During the blanket injection process, the resin was injected into each packer in up to one-half gallon intervals with varied Sealboss 15X catalyst percentages added.

During the Injection it was determined that all perimeter packers in the injection grid would be injected with 15% to 20% SealBoss 15X catalyst added. This percentage results in a more aggressively reacting foam, creating a dam like structure between the slab and substrate, specifically along the perimeter of the injection area. While injecting the perimeter packers the adjacent interior packer was removed to monitor volume of resin needed to make real time adjustments to injected resin volume.

Once all perimeter packers had been injected, interior packers were injected working towards the center of the room injecting in intervals and monitoring resin flow.

The interior packers of the grid were injected with a slower, less reactive foam, catalyzed at a ratio of only five to ten per cent, resulting in a longer gel time, decreased expansion speed and reduced expansion rate — allowing the chemical injection grout to travel much further during injection.

With a varying void depth of up to one inch in an 18’ x 20’ area, 20 gallons of SealBoss 1510 and 2 gallons of 15x Catalyst were used.

Aluminum Injection Packers – Aluminium Injection Packers

Aluminum Injection Packers by SealBoss

Aluminium Packer Advantages

Aluminum | Aluminium Packers for Our Customers Worldwide
Quality Aluminum Construction for Secure Fit During Injection
Very Affordable Injection Packer
The Most Economical Way to Perform Crack Injection
Anti Return Valve in Zerk
A SealBoss Prime Economic Packer – The Aluminum Evolution Packer

Why should I use SealBoss Aluminum Injection Packers | Aluminium Injection Packers ?

SealBoss Evolution aluminum mechanical injection packers save you money.

Modeled after the mighty, tested and proven, SealBoss S-Type steel packer, the aluminum injection packer is an economic alternative and considered an adequate and good choice for many standard injection applications. The aluminum packer is not quite as strong at the limit as a SealBoss S-Type steel packer and does not come in a many variants as the SealBoss B-Type brass packers available.

In conclusion, SealBoss aluminum injection packers are the economic alternative for most standard injection scenarios. They are less expansive and much lighter to carry around, and more affordable to ship.

What is the Limitation of the Evolution Aluminum Injection Packer ?

We recommend to try new packers next to established packers on the jobsite.

It is always a good idea for the injection professional to have a variety of packers on hand. Crack injection applications can be challenging. Badly deteriorated substrates and very tight cracks and cold joints should always be injected with an injection packer of suitable dimensions and design.

SealBoss AL-Type Aluminum Injection Packers -- Aluminium for our non-American Friends

The AL-Type Packers work very well for typical every day injection needs and standard situations. However, for more challenging situations it would be recommended to keep some of the very high quality packers on hand. I would suggest that you give the aluminum packers a try and find out for yourself, if they are suited for your injection requirements.

The aluminum packer is the most economic alternative among the metal type packers and can save you a substantial amount of money an larger jobs.

Please don't hesitate to contact us here at Sealboss for more information about our extensive packer selection. Your representative will be happy to assist.

SealBoss Curtain Injection

Curtain Injection

Bladder / Curtain Injection – Curtain Wall Grouting Method

Curtain Injection Injection Training with Leak Sealing Cube

The objective is to seal below grade block wall and concrete wall structures by the membrane forming, permeation and consolidation capabilities of hydrophilic and hydrophobic injection grout products.

Training is performed using our Leak Sealing Cube mock-up, followed by on the jobsite injection.

The SealBoss Leak Sealing Cube is designed to provide the contractor with an intricate insight into the injection process and chemical grout behavior. Plexiglas equipped cross-sections allow for watching the process from the ‘other side’ – normally hidden in real curtain grouting wall injections on the jobsite.

With the ability to follow the processes during injection on the positive soil-side behind the wall, the trainee gains a good understanding of the injection method and technology.

Procedure Outline

Identify the water source and pattern of moisture intrusion. Most block, stone, and brick leaks are caused by failed positive side membranes. Block walls are often unfilled which also creates voids and pockets for water intrusion. Drill Grid Pattern Drill 3/8 or 1/2 inch holes along the water marks at 2 feet intervals. Moving up the wall, continue to space the holes at 2 feet intervals creating a grid pattern of injection holes as seen in the image. These drill holes are to penetrate the substrate at full depth creating a channel in the wall through which chemicals can be injected.

Packer Install

Once the grid pattern is created, mechanical packers may be inserted into each one. In the case of block walls that are not filled adequately, longer packers are recommended providing a full length channel which ensures that material reached the back side of the wall. it is not recommended to simply fill the blocks with materials – block wall curtain injections require material travel through the entire wall. In the case of older and disturbed stone or brick structures, however, it is also common to inject the structure itself as seen to the right.

For high volume applications, Plastic Button Head Packers are available.

Injection Products and Pumps

Today we focus on SealBoss ® 1510 Curtain Injection Foam and SealBoss ® 15X Accelerator. The single component SB 1510 chemical injection grout is catalyzed with SB 15X Accelerator at variable percentages to either create ‘low foamer expansion’ or ‘high foamer expansion’ properties. Percentages added can vary from 2 percent to 25 percent.

Based on the jobsite and application, a variety of products, such as hydrophobic SealBoss 1510 / 1570 Foam, SealBoss FlexGel hydrophilic polyurethane gel, or SealBoss® 2400 SLV acrylic gel, are available.

Application Considerations

Because backfill and soil consolidation behind the structures are often unknown, applicators must monitor flow rates and material consumption closely.

In scenarios where substantial voids are anticipated behind structural walls, a strategic approach involving the use of expansive hydrophobic polyurethane grout, like SealBoss® 1510 Water Stop Foam, is advised. This material can be injected first to fill these large voids, creating a solid and stable mass that serves as an effective backdrop for subsequent hydrophilic gel injections.

The Stage Grouting Technique

The stage grouting technique is often recommended in such situations. This method involves injecting the product in measured stages with reduced volumes. Each stage is given adequate time to react and form a natural barrier, prior to injecting the next grout stage. This strategic layering and controlled application enhances the overall effectiveness of the grouting process, ensuring comprehensive coverage of product along the outside of the wall and optimal stability.

Sealing Pipe Penetration Water Leaks at Multi Family Apartment Complex

Water Leaks

Multi Family Apartment Complex

Multi Family Apartment Pipe Penetration Leak Stop

A certified SealBoss installer was asked to stop water intrusion and resulting water leaks from a courtyard at a new apartment complex into the underground parking structure below.

The water leakage had been causing unwanted staining and erosion of the concrete floor and was soaking into the fire stop material. It was determined that the persistent water intrusion was caused by rain and the installed irrigation system to water the plants in the courtyard.

The contractor used three different methods to inject SealBoss 1510 Water Stop Foam into and around the pipe penetrations to seal of the areas of where the leaks were significant.

The first method used was a horizontal blanket injection to fill the void between the geofoam and the poured concrete to create a seal around each pipe penetration. This was accomplished by strategically placing injection packers and drilling all the way through the concrete deck into the geofoam.

Next the area was drained and an injection packer was installed for injection of the hydrophobic foam.

After a couple of days the leaks had moved and began leaking around the pipe sleeves.

With the larger penetration sleeves being made of metal, the contractor drilled at a 45 degree angle until he hit the pipe sleeve. SealBoss 1510 leak sealing foam was then injected until positive refusal around the sleeve was seen.

To help assist with containing the reacting material, SealBoss CanSeal Foam was used to as an “instant” backing. The SB CanSeal Foam was also used to fill the voids between the concrete and the ribbed steel sheeting.

SealBoss ® CanSeal Utility Foam is a specially formulated closed cell sealing foam — engineered to fully expand inside the applicator ‘gun barrel’. When the foam exits the tip of the gun it is already fully expanded, enabling you apply exactly as much foam as you need without the messy and undesired “mushrooming” experience you may have with most of the other ‘over the counter’ foam products.

Small Pipe and Pipe Penetration Leak Sealing Kits

SealBoss SealPipe Kit

For the smaller pipe penetrations with a poly sleeve, a Grout Injection Needle was used to inject the foam into the tighter areas. Using open cell backer rod to stuff into the sleeve to contain the reacting resin as the needle was pulled out, SealBoss 1510 Water Stop Foam was able to expand upwards sealing the poly sleeve and stopping the leak.

The contractor was able to stop the leaks and the building owner was notified to reassess the irrigation system for the courtyard above.

How to Permanently Waterproof Tilt-Up Panel Joints with Polyurethane Grout

How to
Permanently Waterproof
Tilt-Up Panel Joints
with Polyurethane Grout

Failing and leaking tilt-up construction joints can be sealed to full depth with single component SealBoss 1570 NSF Certified Water Stop Foam and the Oakum-Soakum Method

Tilt-up Construction Joints are Typically Caulked

Over time, caulks often fail, break open, and allow water to flow into the structure. Caulk failure can be evident as shrinkage of the bead of sealant, delamination (caulk no longer sticks to surface), cracking of the bead, powdering or dusting of the surface of the caulking.

How to Create a New Full-Depth Joint Seal

While caulking creates a small 1/4″ to 1/2″ bond surface with the concrete panel, 1570 Polyurethane Leak Sealing Resin soaked SealBoss Seal-Oakum fibre provides a full-depth bond and seal against leaks permanently. The ‘Oakum Soakum Technique’ is a proven methodology for polyurethane chemical grout installation — creating a permanent seal that remains unaffected by wet, dry, and even in constant water submerged environments.

How to Prepare the Joint

Prior to any remedial repair, the existing, failed caulk has to be removed, and the joint needs to be free of any debris. The joint then needs to be wetted for the water activated grout to react, expand, and cure.

How to Install the Flexible Permanent Seal

To create a permanent seal with the Oakum-Soakum Technique, oakum fibres are first soaked in hydro-active 1570 polyurethane resin (catalyzed with SealBoss 15X Accelerator), and then pushed deep into the clean and pre-wetted joints to form a flexible and uniform seal during expansion.

How to Protect and Finish the Seal for Cosmetic Appearance

After the foam has cured, any surplus of the foam/oakum seal is cut back and finished with an even bead of caulk to provide UV resistance and achieve a matching surface appearance to the other caulked joints.
