Welcome
A simpler, smarter way to manage drainage exits.
Traditional drainage exits can involve multiple materials, including rigid twinwall pipe, stone-wool insulation and mortar, followed by time-consuming internal and external making good.
EXADRAIN offers a simpler solution.
A single, purpose-designed component that can be installed in less than five minutes, providing a neat, uniform finish across every plot.
By simplifying the process, EXADRAIN reduces the need for remedial work, saves valuable labour time and removes much of the variation associated with traditional installation methods.
Designed Around Real Site Challenges
A familiar detail. An unnecessary complication.
Drainage exits are a small part of a much bigger build programme, yet traditional methods can involve multiple materials and separate stages of work.
Even with experienced teams, achieving the required finish takes time.
Across an entire development, those repeated activities become significant. EXADRAIN was developed to offer a more straightforward approach to an everyday construction detail.
Designed for site. Built for consistency

The Commercial Case for EXADRAIN
Across a housing development, the cost of forming drainage exits goes beyond the materials themselves.
Installation labour, finishing requirements and potential remedial work can all contribute to the overall cost.
EXADRAIN offers a more efficient, repeatable approach, with the potential to reduce these requirements across multiple plots.

Developed from experience. Designed for change.
EXADRAIN was developed from repeated real site challenges identified across new housing developments over many years.
Drawing on more than 20 years of experience in the construction industry, founder Matthew Embleton repeatedly encountered inconsistencies in how drainage exit points through external brickwork were installed from plot to plot. These variations often led to avoidable remedial work, delays, and increased pressure on site teams later in the build programme.
Having seen the same drainage installation challenges arise time and again, Matthew developed EXADRAIN, the patented drain exit solution designed to improve installation consistency, reduce risk and remedial costs, and support compliance across residential developments.
The system has been tested and approved, with a strong focus on supporting NHBC requirements, quality assurance processes, and long-term site standards.
Today, Matthew remains very much 'on the tools', ensuring EXADRAIN continues to solve practical site challenges with a solution built around the needs of house builders, site managers, and groundworkers.
