Diaphragm walling

Our equipment is used by diaphragm walling contractors to clean online in support of milling machines and to desand panels excavated by grab. Many clients use our supplementary desilters to work downstream of their own desanding plants where high quality cleaning is required. With rising disposal costs, it is increasingly important to prolong the life of bentonite where possible. We are proud to work with the UK and Europe's leading foundation specialists and in recent years have worked on many projects including London and on the Midlands section of HS2. Our centrifuges and flocculation systems are often used to treat waste bentonite.

POLYTHIN is a particularly effective bentonite mud thinner. One of its major uses is for the thinning (and desanding) of muds in diaphragm walling or bentonite piling, prior to concreting. It is also highly useful for thinning heavily contaminated muds or slurry in directional drilling and slurry shield tunnelling applications.
