Beam Pocket Leaks Sealed

Polyurethane Foam Injection Leak Stop

What is a Beam Pocket ?

A beam pocket is a recessed space designed to hold the end of an intersecting beam in a concrete wall, a masonry wall, or a column.

Beam pockets in exterior structures are often subject to water leakage.

Addressing the Challenge: Comprehensive Water Intrusion Remediation

The Issue at Hand

A notable challenge emerged when a client reported significant water intrusion through beam pockets in an exterior structural concrete wall. This issue led to consequential water leak-related damages within a concessions room and storage area, necessitating immediate action.

To address this critical situation, a specialized waterproofing contractor was enlisted to not only remediate all existing leaks but also to provide expert advice on strategies to thwart future water intrusion events.

Strategic Resolution

The contractor initiated a meticulous examination of the afflicted structure, pinpointing the origin of the leakage on the Northwest side. This area was notably vulnerable due to the accumulation and subsequent stagnation of snow melt, exacerbated by winter storms. Compounding the problem were the compromised gutters and evident signs of water overflow at exterior joints, which facilitated the ingress of water into the structure through various openings, including joints, cracks, and unsealed beam pockets.

To counteract these issues, a strategic approach was employed using SealBoss 1510 NSF/ANSI 61 Water Stop Foam. This innovative solution was meticulously injected into the problematic beam pockets and along the cold joints between the concrete wall and the adjacent corrugated metal, targeting the very sites where leaks had been identified. The application followed the SealBoss 1, 2, 3, 45 Degree Injection Method, employing injection packers positioned approximately 4 inches from the joint. This method involved drilling ½-inch holes at a 45-degree angle, directly targeting the compromised joints for optimal resin injection.

The SealBoss 1510 resin was administered until a condition known as ‘positive refusal’ was achieved, indicating that the hydro-active resin had fully occupied and sealed the intended areas, both in the beam pockets and along the junctions between corrugated metal and concrete.

Proactive Measures for Future Prevention

In addition to addressing the immediate leaks, the client received crucial advice to mitigate future risks. Recommendations included the installation of additional downspouts and the repair of damaged gutters, crucial steps to effectively manage water flow and prevent its accumulation near the building’s foundation. Furthermore, the client was advised to ensure the prompt removal of snow from the building’s vicinity to avoid the formation of stagnant snow melt, a key contributor to the initial problem.

Through these comprehensive measures, the structural integrity and dryness of the client’s property were significantly enhanced, providing a robust solution to a complex problem and laying the groundwork for a drier, more secure future.

Sealing Pipe Penetration Water Leaks at Multi Family Apartment Complex

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.

Example – Polyurethane Injection Grouting Specification

SPECIFICATION – INJECTION GROUTING

HYDROPHOBIC POLYURETHANE
SealBoss 1510, SealBoss 1570, SealBoss 1570 LV

DESCRIPTION:

General

Furnish all labor, equipment, and materials necessary and incidental thereto to perform all required operations to eliminate the flow of water by pressure injection to fill cracks, voids, and joints in concrete substrates.

Definition of Terms

Refusal – when a crack or void area will accept no more grout under the prevailing pumping conditions (for reasons other than the pump-ability of the grout)
Return time – the time taken for a grout, under certain application conditions to completely penetrate a crack, void, or network of cracks.
Gel time – the time required for the grout to cure following the reaction with the accelerator.
Gel time or cure time can be affected by temperature and amount (percentage) of accelerator mixed in the component

INJECTION PROCESS:

Fully examine the existing site conditions to ensure that all associated work can be performed without removing or relocating existing utilities, structures or structural members.

1) Remove all standing water.
2) Drill at a 45˚ degree angle where possible to intersect the wall/floor joint interface halfway through the thickness of the substrate (e.g. 4” deep for 8” thick slab)
3) Drilling depth should be half the thickness of the concrete member.
4) Install mechanical injection ports and secure in place at a spacing of 6-12” inches apart (6” for hairline and 12” for wider cracks). Alternate positioning from left side to right side as you move along the crack where possible. (Often cold joints require same side placement for drilling holes.)
Extremely wide cracks (if any exist) should be covered with a surface seal prior to injection in order to contain the injection resin until cured. Under proper pumping conditions in active leak injection, the following signs should be observed in the order listed:

(a) Water displaced from crack/joint by the resin
(b) Water and resin mix (foamy) appearing at the crack/joint area
(c) Pure resin from crack/joint

If the joint surface exhibits immediate free flow of resin while working the first packer, pause for a few minutes. In most cases the resin will react fast enough with the water and expand rapidly. The resulting resin product will heal the joint and provide a surface seal to contain the material to follow.

The contractor is responsible for estimating what duration time is adequate for grouting the voids and is responsible to prove that the void is full by attempting to inject each port to refusal.

Once the contractor is assured that the resin has reached the next injection packer or has sufficiently stopped the water as evidenced by the grout oozing out of the joint area, he should shut off the resin flow and disconnect pump pressure line and proceed to the next packer.

Follow the injection process for one to three packers, the contractor shall return to the first packer and attempt to re-inject it again. Some of the packers will take more grout, filling up more of the crack/joint area and creating a higher density void filler and water stop.

The contractor shall continue this procedure until refusal.

SealBoss Technical Rep Sealing Leaks In Missouri

Leaks can happen anywhere, and Wine Cellars are no exception.

A local SealBoss Rep was called out to consult on a leaky cellar to demonstrate high pressure injection using the SealBoss P2002 Injection Pump and 1510 NSF Certified Water Stop Foam.

The wine cellar was a renovated below grade structure with a deck/extended porch above. The main source of the leak was a pipe penetration and adjacent crack where mastic crystalline grout had failed.

The repair began by cleaning the area with a wire brush to remove the failed grout down to the concrete. After the area was sufficiently exposed, the crack was clearly visible. A ½” hole was drilled and the SealBoss 13-100AL Evolution packer was then installed and injection with SealBoss 1510 Water Stop Foam began.

Injection continued till the void around the pipe penetration and the crack were filled. The packers were removed and followed by a 5 minute cleaning of the equipment with xylene and followed by SealBoss R70 Pump Flush.
