Stanton Bonna Concrete are part of the major Bonna Sable Group who are Europe's leading supplier of precast concrete drainage products. Its centrally based UK manufacturing facility supplies a variety of products, including circular concrete pipes, manholes, elliptical concrete pipes, concrete pressure pipes, concrete jacking pipes, concrete railway sleepers and GRP sewer liners.

Historically, the production of concrete jacking pipes within the UK has been by either "centrifugal spinning" or by "wet casting" techniques. A third method exists which has been used extensively throughout mainland Europe over a number of years. With this method, pipes are vertically cast using a semi-dry concrete mix with completion being achieved by high frequency vibration. Following an extensive development programme and utilising the experience of our sister European companies, Stanton Bonna have now perfected this technique to consistently manufacture jacking pipes to the high standards demanded by the UK jacking market.

All our concrete jacking pipes comply fully with BS EN 5911 : Part 120 and by the third party kitemark scheme. All our operations are covered by a Quality System complying with BS EN ISO 9002.

Stanton Bonna continues to respond to the needs of the UK drainage market and we have planned additions to our existing product range. Direct contact with us via e-mail, web site or telephone will provide full details of our current range of jacking pipes, inter-jack stations and associated products.
