JKH Drainage Units LTD


JKH Drainage Units Ltd is a leading manufacturer of specialist pre cast concrete products. We are able to engineer cost effective bespoke solutions to solve the problems faced by a wide range of industries. With our highly skilled efficient production team we are able to deliver within tight time scales helping our customers to achieve their contractual obligations. By providing a package that combines a concrete structure complete with the necessary steelwork and/or control gear we can be the one point of contact to solve many of the contractor's on site problems.

As well as our bespoke solutions we have a large range of standard products in stock, many of which can be dispatched via carrier for delivery within 2-3 working days.

We are able to supply technical data, fitting instructions and estimate the working life expectancy of our products if required.


All G.R.C. units provided by J.K.H. are manufactured by casting with purpose made moulds filled with a pre-mix of Portland cement, sharp sand and chopped strands of special alkali resistant glass fibre.

Glass fibre greatly increases the strength of concrete allowing us to create tough products with thin wall thicknesses therefore reducing the overall weight and subsequent cost of installation to our customers.

Technical notes and specification available on request.


J.K.H. DRAINAGE UNITS LIMITED through their fully equipped engineering and drawing office departments have built up a sound reputation for the design and construction of steel moulds for concrete and G.R.C. production and can offer to produce 'one off' special items.
