Drainage Installations

Drainage installations we can provide

Using our varying methods and with our wealth of experience at SW Directional Drilling we can install drainage pipe work of all sizes for all types of waste, be it Conventional, Chemical or even Hazardous. With our great expertise in this sector (over 300 installations) and through working on numerous major contracts over the years, we know exactly how to install drainage to falls as tight as 1:200 and to match the clients needs. The trenchless method of install drainage is fast becoming the only method that a lot of major companies will consider. Negating the need for major excavations, especially with the deep installations and reduction intime taken the benefits of trenchless methods benefits are massive.



With the vast majority of the UK's trenchless drainage installed being in the 100mm to 300mm range, it's no major surprise that we have expertise and unrivalled experience in this field. Although sizes are often on the smaller ends of the scale we have installed drainage up to 600mm in the toughest of ground conditions. One of our most recent projects was to install 330m of 355mm and 250mm drainage for Cowlin through the Bath University complex. The majority of this installation was at 4-5m depth at a fall of 1:200, in solid Limestone! The full installation was complete over 4 shots and within 1 month. This would have took at least 6 months to be installed with other methods, and might have even been impossible. The approximate costing's for the Directional Drilling were 1/10th of the open cut costs.

Below you will find a small list of some of the recent installations we have carried out
