Fortunately for our Sevenoaks customers, we have the experience, the tools, and the expertise to do just that. Whether you want a retrofit basement under your home or a below-garden basement, we can help you.


No matter the nature of your building project, strong and sturdy foundations are an absolute must. At Bon Groundwork Ltd, we offer a range of techniques for your site, depending on the particular specifications. These include poured concrete foundations and pre-cast concrete beams. We can also repair and strengthen any existing foundations that may have settled over the years.


We offer a selection of drainage options to our Sevenoaks customers. From the basic surface water and foul drainage systems that carry natural and waste water to the sewers, to mains sewer connection solutions, we can hook you up in no time.
