Our CSSW CSRT Qualified Surveyors

Pure are very proud to be able to claim two of the basement waterproofing and basement conversion industry’s most highly qualified and experienced specialist structural waterproofing surveyors as highly valued members of the team.

Between them Michael Foster CSSW CSRT MIWSc Dip Surv, and Sean Tristram Jones CSSW CSRT CRDS have over 55 years industry experience.  This admirable level of knowledge and experience ensures that Pure’s clients receive the best professional advice on their basement waterproofing and conversion projects.

Michael Foster

Michael Foster started gaining his 30+ years construction industry experience labouring for his dad’s building company in West Yorkshire in the 1980’s at the weekend and during school holidays.

Upon leaving school he went to Leeds College of Building where he successfully completed a BTEC Certificate in Building Studies whilst working for a local construction company on the tools.

Once qualified, Michael joined his two older brothers who were also in the building trade for a few years before starting his own small building company.

Having gained several years general construction experience Michael returned to study part time, at the British School of Waterproofing where he qualified as a Surveyor in Basement Waterproofing. He then began to successfully specialise in basement waterproofing works.

A couple of years later, Michael was approached by a national basement waterproofing contractor whom he had been successfully in competition with and offered a role with them as a Basement Waterproofing Specialist Surveyor.

Progressing from a surveyor to a Regional Manager in just a few years Michael was instrumental in expanding the company’s basement waterproofing division nationally.

Michael’s construction experience and conscientious approach to his work led him to be invited to join South Leeds Builders Merchants as a Product Manager.

He again progressed within this business to the role of Marketing Director.

Still interested in pursuing his interest in construction and particularly in the field of basement waterproofing, Michael continued to study part time gaining several industry recognised qualifications including a Diploma in Surveying Practice from the College of Estate Management, a CSRT (Certificated Surveyor in Remedial Treatments) and CSSW (Certificated Surveyor in Structural Waterproofing – a specialist qualification only about 350 people in the UK hold!

Michael was also trained by international waterproofing systems supplier Basement Systems Inc. in America in basement drainage systems and sump pumps.

Now a leading UK certified and experienced basement waterproofing specialist, Michael returned to a national waterproofing company in the role of Special Projects Manager before deciding to start Pure Basement Systems in 2010.

Pure Basement Systems’ clients benefit from Michael’s extensive specialist basement waterproofing knowledge and experience as well as his 30+ years of general construction experience and the expert advice he is able to offer from the design phase of projects right through installation to completion.

Sean Tristram Jones

Sean started his successful career in the industry as a technician with a well respected national company over 25 years ago.  He stayed here for several years honing his technical skills and developing a robust understanding of the industry.

He then progressed to a more supervisory role for a few years with another national company where he developed his project management skills.

Sean then moved to successfully running his own company for the next 8 years, further enhancing his comprehensive skills and knowledge of the basement waterproofing and basement conversion industry until he was approached  by another national company and recruited as a branch manager / senior surveyor where he stayed for several years.

Sean’s next move was to a role incorporating business development, specialist surveying and project management for two years before he made the exciting decision to project manage and self-build a 5 bedroom property. It was at the end of this project that Pure approached Sean as a recognised and experienced specialist in the field and recruited him to our team.

Sean is an experienced basement waterproofing and basement conversion specialist surveyor.

As you can see from the above brief summary, Sean has gained considerable experience over many years in the industry with several national companies as well as his own smaller business, providing clients of all sizes with expert advice on their basement waterproofing and basement conversion projects and converting this advice into high quality finished projects.

Reasons you might require a CSSW Surveyor like Michael and Sean

Basement waterproofing and basement conversion represent a significant investment in probably your biggest asset, your home.  It is a very specialist area and should only be attempted by qualified and experienced contractors who can offer you a professionally designed and specified bespoke waterproofing system designed to BS8102:2009 by a CSSW qualified surveyor.  Your chosen contractor should also be able to offer you plenty of checkable references from previous satisfied clients and be able to offer you not just their own guarantee but also the option to purchase an insurance backed guarantee from a recognised scheme to provide you with peace of mind for many years to come.

New Build Guarantee Schemes such as NHBC and Premier Guarantee now also require that all new build basement waterproofing systems are designed by a CSSW Qualified Surveyor.  With two suitably qualified and highly experienced surveyors on the team, Pure are able to assist with these projects.

Michael, Sean and the team at Pure Basement Systems have built up a solid reputation for providing clients throughout Yorkshire, Cheshire and Manchester with expert advice and professionally managed basement waterproofing and basement conversion projects completed to a high standard.  If you want reliable, professional advice on your basement waterproofing or basement conversion project, contact us today for a free consultation with one of our CSSW specialist surveyors.
