Design, Supply & Install

At MacLennan we not only complete projects successfully and to the highest standards, but also to add value to our clients by giving them full design and technical support from the beginning to the end of the project.

Qualified Staff

All of MacLennan’s waterproofing staff are trained to an extremely high standard: including monthly refresher courses at our own facilities and training days in partnership with our suppliers. MacLennan’s workforce is one of a few in the country to hold NVQ Waterproofing qualifications.



We design and install for new build and remedial projects. We have as regular customers numerous Architects, Engineers and Building contractors.

MacLennan take over full responsibility and liability for the basement waterproofing design. This is backed by specific waterproofing professional indemnity insurance. MacLennan then supply and install the deck and basement waterproofing so there is no split responsibility this is backed by our full products insurance. This is not available to most waterproofing contractors to give.

This is supported by a GPI insurance, but you should never rely on the GPI insurance alone. It is the products insurance that gives you the protection you need.The waterproofing system is then serviced and maintained by our NICEIC qualified technicians.

All of this service is protected by our FSA regulated insurance. We are one of the very few who can offer this level of protection.We train all staff in-house and do not use sub-contractors for basement waterproofing solutions.

If it needs waterproofing we know the best system for the job and we are qualified to design and install it for you!
