Sealocrete is the UK's leading independent manufacturer of lightside building
materials, chemicals and construction products.
Established in 1934 the company's innovative waterproofing, dustproofing and
coloured concrete admixtures played a major role in construction in the Second
World War and in rebuilding postwar Britain. Sealocrete produces over 90% of
its products in-house so that it can maintain quality control and offer superior
Sealocrete products include concrete admixtures, adhesives, decorating products,
floorings, wall coatings and concrete repair products. Sealocrete products are
available through Builders Merchants across the UK.
From Small Beginnings
Sealocrete was founded in Middlesex by Mr Eric Haes in 1934. At the outset there
were just two full time staff and a part time assistant, and the product range
comprised of just three materials – one of which was the forerunner of
today’s highly successful Sealocrete Double Strength Premix. By 1937 the
name of Sealocrete was already established in the building industry.
Innovative Products To Aid The War Effort
In 1939 Sealocrete moved to larger factory and office premises in London. Between
1939 – 1945 many of Sealocrete’s products were used to assist with
the War Effort. For example, Sealocrete was the first to supply admixtures to
enable concreting work to be carried out successfully during frosty weather.
This enabled a concrete roof to be constructed on an army camp in Richmond Park
during the icy 1940 winter. Sealocrete products were used to dustproof and waterproof
aircraft, arnament factories and Ordinance depots. The concrete passage floors
under Whitehall, which connected the wartime offices of the late Prime Minister,
Sir Winston Churchill and his staff were also dustproofed by Sealocrete.
Sealocrete Waterbar and Sealocrete Double Strength Premix were used as waterproofers
in the construction of the Mulberry Harbour, which played an important part
in the landing of Allied troops in France in 1944. Sealocrete Double Strength
Premix was also used to waterproof concrete rafts and the internal renderings
and mortar joints of storage tanks built to provide water for fire fighting
during the blitz. Then, as now, Sealocrete provided full technical support for
these innovative projects.
Sealocrete also played an important part in the rebuilding of post war Britain.
Sealocrete’s Sealotone Cement Colours were widely used to create the coloured
concrete floors specified by the Government for the council homes built in the
post war period. The demand for Sealotone was high and Builders Merchants throughout
the country began to stock the product. This was the start of the close links
with the Merchant trade, which Sealocrete continues to maintain.
Shortly after the Diamond Jubilee of Sealocrete in 1984, Mr Haes died and Sealocrete
was the subject of a Management Buyout. In 1988, control of the company was
bought by the Nullfire Group based in Coventry.
A Period of Expansion
Meanwhile, in 1971 Mr Michael Kelly founded PLA Products in Rochdale, where
six products were produced for sale to Builders Merchants. In 1974 the number
of products manufactured and the number of Builders Merchants customers supplied
by PLA Products increased so much that the company moved to a 12,000 square
foot factory at Norden, Rochdale. This was later expanded to include a 15,000
square foot warehouse.
During the next ten years, PLA Products’ continued to grow. Glazing and
DIY products and Sealants were added to the product range, and the Builders
Merchants product range was also extended. By 1984 the company outgrew its 27,000
square foot facility and acquired 60,000 square foot premises on four acres,
which it currently occupies.
In 1992 PLA Products purchased Sealocrete from the Nullfire Group creating
the existing company. Sealocrete’s operations were moved to Rochdale and
a 17,500 square foot distribution centre was purchased.
In March 1998 Sealocrete decided to add paint to its product range to enhance
the offering to its customers. As the company has a policy of manufacturing
its products in-house Sealocrete purchased a paint manufacturing business in
Sealocrete recognises environmental management as an important responsibility.
Evironmental matters are a prime duty of management and an area where every
employee has a contribution to make and the company trains and encourages staff
to operate in an environmentally responsible manner. The company does everything
- Meet or exceed the requirements of all relevant environmental laws and regulations
and will adopt responsible standards where no regulations exist. It will seek
to continually improve environmental performance.
- Carry out environmental audits and measure against set targets.
- Have and develop products and processes that are intrinsically safe and
do not cause environmental damage. New products and processes will be assessed
for environmental impact at an early stage of development; they will also
be assessed for efficient use of natural resources and energy and for the
safe and responsible disposal of residual wastes.
- Communicate with employees, the public, customers, distributors and contractors
on environmental matters including actual and potential hazards of processes,
products or wastes and will seek to work with industry, academic and official
bodies to gain and spread relevant knowledge.
- Run its business in such a manner as to minimise incidents and emergencies
but will in any case maintain and develop procedures to respond quickly and
effectively if and when these occur.
