## Description

The Acta-Leak Crack Repair Kit fixes water leaks in concrete foundation walls with single component Hydra Stop 300 polyurethane foam. There is no mixing two parts to make the foam react and expand. This kit can be used on actively leaking basement wall cracks, foundation cracks that have been previously repaired or are less than 0.02” in width. The Hydra Stop 300 hydrophobic polyurethane foam is injected with over 1000 psi of force with the included grease gun through 3/8” injection packers. The Hydra Stop 300 polyurethane foam fills the crack entirely, from inside to outside of the wall. All work is done from the inside. The kit contains enough material to perform 10 feet of leaking concrete foundation crack.

## Customer Reviews

### ⭐⭐⭐⭐⭐ IT WORKED! Saved me over $9,000
*by A***O on July 10, 2023*

First off... be prepared to get real messy and throw away the grease gun when finished.PRO: Saved about $9,000 from professional quote. Professional job was no warranty either since houses can resettle in my area often. BUT LEAK HAS STOPPED! Crazy rains in Broomfield, CO this year. I'll be the first to update review if leak starts again. Have about 1/2+ bottle and 10 more fittings if needed. Took about 3 hours by myself.CON: It's a 2 person job... the grease gun will not hold onto zirks by themselves. The grease gun leaks bad when you try to add the last amount per directions. Foam seals up and you will push chemical out the seals of grease gun. The gun is a one time use, so hurry and do all the zirks in one-go. Also, the bags on inside of gun are a major PITA. Have to really position so it doesn't cover inside of grease gun. Lastly, I'd pump in a massive amount the first time, but only one time if had to do this again.

### ⭐ Did not expand and ports don’t seal
*by T***. on December 24, 2020*

Foam only expanded 2-3 times despite being stored at 70F prior to use. Ports did not seal in CMU block wall. May work better for poured concrete. Either way with both problems and messier application I will ask for a refund and suggest you save money by drilling narrower holes and just buy a standard can of expanding foam with a straw.

### ⭐⭐⭐⭐⭐ Better than what the professionals use
*by J***A on August 17, 2018*

This stuff rocks! Sealed a stubborn crack in my concrete foundation that a well known company couldn’t fix after several tries and years.
