Speeding up Construction With Versatile Products
SuDS Drawpits
SUDS Drawpits are a range of innovative structural access chambers for underground installations. Ideal for water utilities and other ducted network applications where access chambers are required for inspection and maintenance, SUDS Drawpits are suitable for all footway and highway projects.
SUDS Drawpits chambers are formed by interlocking rectangular rings.
SUDS Drawpit parts are manufactured from recycled polymers and can be recycled at the end of their life. They are able to withstand high loading forces which means that a concrete
backfill is not required.
Applications SUDS Drawpits can be used to create metre boxes, hydrant boxes and chambers for many other applications
Due to its lightweight plastic construction and reinforcement webs the SUDS Drawpits will incur less breakages and can be installed without the use of lifting equipment like conventional concrete chambers.
DIMENSION LAYOUT
SIZING INFORMATION
SUDS Drawpit rings come in 150mm deep, with 150x150mm and 430x280mm rings also available in 50mm and 25mm depth lightweight and easy to install. SUDS Drawpit rings are also able to support both B125 up to F900 loadings for some sizes.
QUICK GUIDE TO CHAMBER INSTALLATION.
Any depth is available, although greater depths on chambers of large width or breadth may need reinforcing.
1
Dimensions of excavation:
Length x Width x Height. Please allow additional depth for cover and frame required plus the mortar bed.
2
Pour a concrete base to act as the foundation. Alternatively dry mix or compacted stone may be used. Thickness
of the base is of the preference of the onsite engineer.
3
Lower the first section of the chamber into the excavation. Push the first section down into the wet cement making sure it is centered and level.
4
Insert the remaining sections making sure they are correctly aligned.
5
Lower the access cover on to the chamber once the concrete base has set, using mortar or grout as required.
6
Check the fit of the access cover making sure no debris is stuck in between chamber and frame.
7
Pack the as-dug material from the excavation process into the cavity between chamber and excavation and compact it.
8
To finish off the installation, lay your finishing material up to the access chamber frames edge.
Remember...
The chamber must be braced by a strut/struts to prevent the backfilling process to cause side wall deflection, for chamber wall lengths of 900mm and above.
When the chamber is braced, backfilling can take place at 300mm deep sections at a time.
