Type C Cavity Drainage waterproofing
You’ve probably heard the term “waterproofing” and think it refers to a single product or system. But there are different types of waterproofing systems out there.
Onyx basement services has the solution to this problem. We specialise in type C waterproofing systems that will keep your basement dry for good! This involves using a high density polyethylene (HDPE) studded membrane which is installed and applied to the walls and floor. We then use drainage channels leading the water to a sump/pump or existing drainage system.
Our team is dedicated to providing you with the best possible service at an affordable price. Here’s how we do it – our contractors will work closely with you throughout the process of installation so that they understand exactly what you want to achieve from a design perspective as well as a budget perspective. We’ll also work within your timeframe so that we can complete the job when it suits you best. Whether you need us there today or next month, we’ll be there when it counts!
