Keeping it simple

RAIN! RAIN! and more RAIN!

According to Metservice.com many areas in NZ “was a sopping wet April for much of the country, with rainfall ranging between 200% and 350% of normal over the entire North Island and the north and east of the South Island”.

“This followed on from extremely wet March in many of the same regions, meaning it was the wettest March-April period on record.”

That is a lot of water and often it is only when we have a torrent of rain that drainage issues become apparent.

CHECK YOUR DRAINAGE BEFORE THE STORM

We know winter is on its way when temperatures drop, the days get shorter and the nights get longer.

It may be wise to check for any drainage issues before the inevitable deluge occurs. Undirected water can cause a lot of damage and can be expensive to rectify.

Like other drainage systems our HYVOL surface water catchment channels and grates need some maintenance to ensure water flows correctly.

Leaves and other debris can prevent maximum surface water from flowing into the channels. If there is no grate security in place, the grates can be removed to allow the channels to be washed out. If there is grate security these can be undone or it may be possible to direct water under pressure from a hose or water-blaster to remove the debris without removing the grates.

If you have a HYVOL sump remove the grate and check for any build-up of silt inside it.

Regular checking of any drainage systems are recommended.

If you find a drainage channel or grate needs to be replaced even if they are not our HYVOL drains contact us or phone 09 832 9088.

Installation Guide Drainage Channels

Information on how to install your HYVOL® surface drianage channels.

1. Setting Up Drainage Channels

Position channels to line and grade on concrete support pads approximately 100mm from each butted joint. Leave until concrete pads have set.

2. Encasement with concrete

Encase drain channels to the minimum dimensions using high density concrete

Increase dimensions of the encasement concrete and reinforce with steel as necessary for the intended load and usage of the channels and site substrate stability.

Encasement concrete should be installed using acceptable engineering standards e.g it should be isolated from adjacent concrete by construction/contraction joints. These should also be applied to control longitudinal shrinkage of the encasement concrete.
