Marshalls Civils & Drainage concrete gullies are typically used on roadways for surface water runoff.
Precast concrete road gullies are manufactured to BS5911:2004 Part 6 and are produced monolithically on fully automated machines, providing a strong robust unit that requires no concrete surround and is not subject to floatation.
Road Gully advantages include:
- Strong and robust due to it being manufactured on fully automated machines.
- Does not lose shape, the gully pots are composed of concrete, stronger than plastic.
- Not subject to floatation due to the concrete material ensuring a heavyweight product.
- Quick and easy to install, delivered in a one piece unit.
- No concrete surround needed due to its concrete composition.
The gully adaptor is a versatile elastomeric sealing adaptor ring manufactured in EPDM rubber to BS 2494 Type D and available to complement the above product.
The procedure for installation and selection of gully adaptor are as follows:
- Ensure the gully outlet socket is clean. Any hard points should be removed.
- Fit adaptor into socket. The adaptor seals are designed slightly larger than the socket to ensure a positive location and an effective seal. Care should be taken to even out the seal to remove folds, although if left, this will occur naturally.
- Place pipe in adaptor and push home.
Lubricant requirements:
- Smooth plastic pipe – requires no lubricant.
- Supersleve pipe – can be jointed dry with care, but lubricant may be used to assist jointing.
- Densleeve/Hepseal/Corrugated pipes – lubricant such as water/soap, silicone etc. is required for jointing purposes. In some instances for corrugate.
