We sometimes see rain water leaking into homes because they do not have a proper waterproofing membrane. Most often, we see that tar based or silicone materials have been used on footings, walls and joints etc. Overtime this methodology gets compromised by sun, wind and rain. Then, inevitably, water seeps through.
How To Stop Your Yard From Flooding in the Rain
- Regrade your yard. The “grade” of a property is another word for the incline or slope of the land that it is on. ...
- Install a dry well. Soil has a lot to do with drainage, and some soils absorb water faster than others. ...
- Plant a rain garden. ...
- Invest in a sump pump.
Rain chains. Divert your water with a rain chain if you have a grassy area nearby. Rain chains can be made of copper or aluminum, and they're usually long, chain-like structures as tall as your home. Hook a metal rain chain onto the side of your home where the water collects the most.
Ideally, the ground should drop one inch for every one foot that you move away from the house for the first 5-to-10 feet around your house. While this is not always possible, the ground should never be sloping upwards as you move away from your house foundation.
Mulch is yet another excellent way to help prevent flood damage to your yard and your home. Mulching around your house and around gardens or any lined areas that you have plants or soil is a great way to help absorb as much rainwater as possible.
When it comes to flood control, the best lawn is a natural lawn. The best plants for flood control are native plants. Native grasses are preferable as they are ideally suited to the climate they grow in and are usually hardier and more drought resistant.
To prevent water ingress through brickwork you should use a water repellent or façade cream such as Remmers Funcosil or Microshield Ultra. These products penetrate into brick, stone or concrete to provide long-lasting water repellency to building façades. You can browse our full range of Water Repellents.
Any joints in your concrete floor also invite water to seep in, and the best way to stop water in these areas is to seal them up with exterior-grade caulk.
In many cases, rain penetration is caused by poorly designed or maintained building details (e.g. blocked downpipes or leaking gutters) causing large amounts of rainwater to flow over a small section of masonry. In these cases, the penetrating damp can usually be cured by rectifying the defect.
Wall ties failing can lead to water seeping into your property, as a bowed wall is ineffective against the elements that it is meant to be protecting your home from. This then can allow moisture to travel to your properties inner wall leaf, and seep into your property from there.
It's simple: concrete doesn't absorb water; grass, shrubs and trees do.
In a 1990 study comparing 15 different organic mulches, wood chips were one of the best for holding moisture, moderating soil temperatures, controlling weeds, and overall sustainability. Wood chips absorb more water than many other mulches, water which both cools the soil and is slowly released to plants.
Materials to improve drainage in soil include organic or inorganic amendments. Organic amendments have the added capability of providing additional organic matter and nutrients. Amendments can include bark and wood chips, compost,and pea gravel, depending on soil type.
Sewers and lateral drains connected to the public network used to be the responsibility of the property owner. However, most are now maintained by local water companies. If you have any problems with your sewer or lateral drain, for example if it's blocked, contact your local water company.
Impervious surfaces include your roof, driveway, patios and lawn. Reduce rooftop runoff by directing your downspouts to vegetated areas, and not to the storm drain on your street. For your driveway and patios, consider putting in permeable paving or patterns of cement and brick that allow water to filter through it.
Retaining walls do not completely stop water, but they do manage overflow and prevent soil from sliding. When it comes to drainage, your retaining wall should have drain holes or piping to direct water away from your property.
Gravel Beds Provide Natural Drainage
Water drains more quickly through gravel compared to most types of soil, so puddles form less-readily on gravel-covered pathways and borders than they do on soil surfaces.
First, remove any vegetation or mulch in areas that need grading. Your grade needs to be no less than 1” per foot, up to 10' from your home. Add topsoil so that you have a continuous slope around your entire home perimeter. Once added, tamp the soil down, add more if needed, then smooth the grade with a metal rake.
Take grass out of the negative drainage area and put it to the side, making sure it is at least 6 to 10 feet from the house. Add at least 8 inches of new soil to raise the grade and this should force the water into the other direction.
