Deck Waterproofing Dorset

🏡 Project Complete in Dorset! 🏡

We were called in to tackle water ingress issues at a beautiful property in Dorset, where the client was dealing with a leaky basement and deck area.
Our team installed a full cavity drain system in the basement and fully waterproofed the deck area above, ensuring no leaks will penetrate below.
Here's how we did it:

1. Preparation: We made sure the area was clean and dry to ensure maximum adhesion and prevent outgassing.
2. Primer Application: We applied the primer to create a solid base.
3. PolyM System: Our flexible liquid PolyM system was then applied. This solution is perfect for decks, buried roofs, and retaining walls, even in colder temperatures. It's fast-curing, highly durable, and hard-wearing.

London Radon Protection

We're thrilled to be working with new clients on an incredible restoration and refurbishment of an existing house in London. This project includes the addition of a one-level basement that will feature a guest bedroom, gym, and utility room. 🏡✨

As local authorities become increasingly concerned about radon, we're seeing more projects that require radon protection measures. Starting from February 1, 2023, all new construction plots must have radon protection measures installed in accordance with updated mapping to comply with NHBC Standards and Building Regulations. 🛠️💧

While radon gas may not be as prevalent in London as it is in areas like the South West, it's still a significant concern for property owners. Radon gas can affect properties and their occupants across the UK, and it's important to be aware of this issue.

Electrical Testing Deck Waterproofing

Ever wondered how we guarantee our completed decks remain leak-free? At MacLennan, we take quality assurance seriously, and one of the key steps in our process is electrical spark testing. This crucial test is performed before we provide our long-term guarantees, ensuring your deck is perfectly sealed and protected.

What is a spark test? 🤔

A spark test is a highly effective method for detecting even the tiniest defects in waterproof materials. By passing an electric current through the material, we can identify minute pinholes and imperfections that are invisible to the naked eye. This allows us to confirm the integrity of the waterproofing and address any issues before they become problems.

Our commitment to quality means you can trust that your deck will remain dry and durable for years to come. With MacLennan's thorough testing and long-term guarantees, you can have peace of mind knowing your investment is protected.
