Underground waterproofing solutions on large construction sites.

---

Watertight has years of hands on experience in below ground waterproofing systems. We know which products are the right products to use for each situation. We are constantly undergoing underground waterproofing solutions on large construction sites and smaller residential projects. Our trained applicators use the correct product, the correct way.

The types of work and products we most typically use  are:

• ​​Bentonite Tanking - We use bentonite to wrap the footings of buildings on big construction sites. Bentonite is then used under floor slabs and up basement walls. In hard to access areas Watertight can attach bentonite to concrete panels at the factory when the panel is made
• Sika blackseal SB – Spray on bitumen membrane used in waterproofing situations both above and below ground, protected and not exposed to sunshine
• Sika Blackseal Plus – paint on bitumen waterproofing membranes used as tanking on buildings
• Flexible PVC waterbars used in new concrete structures 
• Polyurethane sealants that swell up when in contact with water, typically used in conjunction with  bentonite in cold joints between concrete pours on site
• Fully bonded FPO sheet membrane waterproofing systems for basement and other below ground structures. We can wrap underground concrete areas with the membrane and terminate the membrane to be trapped by concrete pour.
• Peal and stick waterproofing membranes
