Maximising space is likely to be high on the wish list for those of you self building a new home. One way to do that is to include a basement storey. If this forms part of your plans, it’s essential to prioritise waterproofing from the outset. A properly protected basement ensures a dry, safe and habitable space that will give you peace of mind long into the future. So, what are the key factors when waterproofing new build basements, why is it important to engage certified waterproofing designers from early on in the project, and what are the associated costs?

Certified designers

Before delving into the technicalities of waterproofing, it’s imperative to understand the importance of involving certified waterproofing designers from the very beginning of your scheme in order to get the outcome you desire. “It is now a condition that a waterproofing designer or a waterproofing expert be involved in self build projects,” says Anthony Spinney of Glatthaar. “An expert will craft the right solution. What are you are prepared to accept? Do you want a dry, warm environment, or are you happy with a basement that potentially has continuous water ingress that has to be managed by a pump 24/7?”
