An advantage of MacLennan’s Polyprufe over other systems is that it fully bonds to a variety of substrates so water cannot track under it. Polyprufe is seamless so there are no joins or joints to fail. Liquid coatings are elastic, so they are also crack bridging. Liquid waterproofing is seamless. They are quick to install and the most robust, well-bonded system available. The systems are trafficable within 24 hours. MacLennan qualified, and experienced technical advisers are available to provide specifications that comply with all codes of practice and are covered by our own PI for design.
