Resin Injection is a proven and successful system where a structural crack has appeared in your shower, balcony, pool or concrete surfaces. The scope of works involves grinding out the crack to a suitable depth and injecting the area with resin to bond with both existing surfaces.
This system also when suitable works well in a shower where the fall in the floor tiles is a poor design and the water pools against the wall and floor area prior to draining towards the waste.
This will not improve the drainage of the floor, silicon when in the wall and floor area is not designed to be submerged under water and will fail, but will stop water leaking into the internal wall joint.
Resin injection fails when the correct prep work is not carried out and should only be installed by licensed waterproofing contractors who understand the products limitations.
