Basement Construction

With basements waterproofing is paramount. The most popular way of ensuring a watertight basement is using a special additive in the concrete called caltite and a method of construction that accompanies it. We are highly experienced with this system and work closely with the manufacturers of the additive to achieve the best results, even in the wettest of conditions.
