Waterproofing membranes have evolved a lot in the past few years. That said there always seems to be numerous products on the market. So what makes a waterproofing membrane valuable, and how do you recognize what is the greatest product for you?

What is the perfect waterproofing membrane?

A perfect waterproofing membrane should provide the following benefits:

1. Preserve the substrate from moisture

2. More elongation before breaking point

3.

4. Dry without being stressed

5. Be capable of being bonded (eg. with tiles)

5. Have more chemical and abrasion resistance

6. Be easy to implement

7. Be safe to deal and non-toxic

Currently, there are two general categories of waterproofing membranes: acrylic and polyurethane. Polyurethane has a larger tensile strength and elongates much. Although, they typically have solvent based things that are little harmless to use. Bonding to them can also be difficult. Acrylic usually needs much longer to dry and is little resistant to abrasion and some key chemicals.

Good waterproofing membranes need to give a waterproof hindrances but it must also encounter assumed movement. Such movements, such as that at junctions, can easily be adjusted with bond breakers. They allow the waterproofing membranes to stretch rather than snap, taking advantage of the stretchable feature of the substance. The key idea is much like an elastic band. A big part of elastic will expand further prior to snapping than a short piece of the same material.

The difficulty with sudden movement

The obstacle exists in how much the waterproofing membrane has to enlarge to accommodate sudden cracks (those not addressed with bond breakers). Because the expansion (mobility) is more than the elongation (stretch) ability of the waterproofing membrane, it will lead to a tear in the membrane potentially leading to leakages.

Thus actually if the movement is more than the waterproofing membrane can stretch out, then it will snap. A bond breaker allows the membrane to expand a lot more.

THE SOLUTION

Installing the needed bond breakers is usually necessary. Although the form of the membrane can also help. A waterproofing membrane that is harder with much stretching power means that it is a lot forgiving and the bond breakers can be narrower. Essentially the better the elasticity, the later it will break and the stronger the membrane’s interior (or tensile) strength, the more possibly it will de-bond and extend instead of snap. Remember that it is always good to install a bond breaker in all parts that are going to move.

Basement waterproofing membranes once done become very difficult because the water pressure is from the negative side, the difficulty arrives when a waterproofing membrane could not survive hydrostatic pressure from within just the substrate and so fails. Water may enter a basement by a number of ways such as through joints, walls, or floors. A number of basement waterproofing membranes handle such problems.
