IBS Stoplogs are ideal for use when temporary water arrest is required and a conventional penstock is excessive in design and cost.
They are generally used temporarily for diverting flows whilst carrying out maintenance or for creating a weir wall.
Stoplogs, like penstocks, are used in a wide variety of applications and installations including but not limited to:
Installation of IBS stoplogs is easy, principally due to the extremely flexible ground seal that we use;
This means that the IBS stoplog system usually consists of only 2 main components: the frame sides and the logs. For many installations, an invert frame sections is not required (unless the frame is mounted in front of an opening up a wall or in the case of stainless steel stoplogs), so this presents a cost effective solution in terms of purchase price, installation costs and construction preparation work.
IBS Engineered Products supply aluminium or stainless (304 or 316) stoplogs in a variety of width and height profiles, according to the size of the channel/aperture and height of water to be retained.
Frames are available in stainless steel BS EN 10088 grades 1.4301 (304, 1.4401 (316) or 1.4404 (316L), depending on the application and required specification.
Frame mounting options include standard channel rebate, channel sidewall, wall face (on or off-seating), plus special angled or stepped solutions. For extremely wide openings, it is possible to use removable or permanent stanchions to split the logs in to shorter sections.
Pressing tools are provided with each stoplog system to ensure that the ground and intermediate seals are compressed, thereby effecting a greater level of seal than that of other stoplog systems.
