UK Patent No. - 2542850

Developed over the past 20+ years, our Glass Reinforced Plastic (GRP) range of catch-pit sumps, raising frames and covers represent a revolutionary development within the field of railway catch-pit design and construction. Our range of GRP Catch-pit products are:

  • 75 - 90% quicker to install than the equivalent concrete system.
  • Available in three different sizes, ‘Narrow’ (‘Matisa’ equivalent), ‘Luton’ and ‘Standard’.
  • Both Narrow and Standard Sump’s and Covers are compatible with concrete frames.


Durham GRP Sump Units are:

  • Typically installed for ‘Cess’ Drainage.
  • Typically installed as a catch-pit over 1.2 m’s deep, sump invert to cover level, and/ or when a larger diameter pipe is required as it can accommodate a 450mm ID (510mm OD) pipe with matching sump.
  • Suitable for use with either PCC Raising Frames or Derby GRP Raising Frames
  • MAX Inlet / Outlet hole Ø 510 mm.
  • Can be fitted with Rubber Stone Guards, to prevent ingress of granular material during installation.
