Wall drainage of the foundation: disassembly of the technology of carrying out works with their own hands

The foundation is a major factor in keeping our homes warm and energy-efficient. But what about wall drainage, an aspect that is frequently disregarded? This crucial element guards against moisture damage and the growth of mold by preventing water from penetrating into the foundation. We’ll dive into the DIY wall drainage installation process in this guide, dissecting each step so you can approach it with confidence.

Recognizing the function of wall drainage in upholding a dry and stable foundation is the first step towards appreciating its significance. Water can build up around the foundation without adequate drainage, which over time can cause problems like leaks, cracks, and even structural damage. Not only will an efficient drainage system protect your house, but it will also increase in value and lifespan.

Getting the required equipment and supplies together is essential before getting down to business with the installation. Having everything you need on hand, including waterproofing materials, drainage pipes, and digging equipment, will expedite the process and reduce delays. To guarantee compliance and safety during the installation, you should also become familiar with the local building codes and regulations.

Now that you have the necessities, let’s go over the exact steps involved in installing wall drainage. To reveal the outer walls, you must first excavate the area surrounding the foundation. To provide the drainage system access, this entails carefully excavating trenches around the perimeter. Use caution to prevent harming subterranean utilities or existing structures.

When it is necessary to build a wall drainage?

The necessity of performing repairs on the wall drainage device is determined by the specifics of the land plot. But in several situations, these tasks are required:

• at location of buried parts of the house below the calculated level of groundwater occurrence;
• at installation of basement floors at a height not exceeding half a meter above the calculated groundwater table;
• in case of construction of exploited buried premises on clayey and loamy soils, the presence of underground water does not play a role;
• placement of structures in the zone of action of capillary humidification and inadmissibility of the appearance of dampness in the premises;
• Technical undergrounds in clay and loamy soils, if the project provides for their burial by more than 1.3 meters from the ground surface.

In addition to installing a foundation drainage device, it is mandatory to erect a screed with a 2% slope and a minimum width of one meter around the entire perimeter of the object in order to prevent the territory’s soils from being watered and to restrict the amount of water that can be used for residential and commercial constructions.

High-quality soil compaction, which is done in compliance with current standards when backfilling trenches and excavations, can resolve this issue. Regardless of whether foundation drainage is present or not, a protective layer of waterproofing is applied to the building’s ground-facing components. Wall drainage is not set up when building a home on sandy soils that allow water to readily percolate into the lower soil layers and do not freeze in the winter below 80 cm.

Plan for a wall drainage system that guards against groundwater flooding of the house’s underground structures

In the article "Wall Drainage of the Foundation: A DIY Guide," we"ll break down the process of installing wall drainage for your home"s foundation. Wall drainage is crucial for preventing water damage and maintaining a dry, healthy environment inside your house. By following our step-by-step instructions, you can learn how to carry out this essential task on your own, saving both time and money. From preparing the site to installing drainage pipes and backfilling, we"ll walk you through each stage with clear explanations and practical tips. With a little effort and the right guidance, you can successfully complete wall drainage for your foundation, ensuring long-term protection for your home against moisture and related issues.

General norms and requirements

The wall drainage system is installed following the building’s contour, starting from the exterior. The foundation’s design width and the precise placement of manholes determine the size of the gap between the drainage pipe and the building wall. The base of the strip foundation or the base of the foundation slab should not be lower than the depth of the wall drainage system. It is permissible to install drainage above the foundation sole if the foundation structures are situated at a significant depth as long as precautions are taken to avoid the drainage system’s components subsiding.

It is advised to use geocomposite materials, which are made of plastic profiled membranes glued with geotextile on one side, to save on sand and minimize construction costs. Because of their distinct surface area, drainage membranes not only keep the foundation dry but also effectively direct water to the perforated pipes. In addition, water can freely flow through the geotextile filter, capturing soil particles that have been drained.

The thickness of the layer filtering bulk materials can be reduced by using a two-layer profiled membrane.

Selection of drainage pipes and their installation in trenches

The type of material used for drains (perforated pipes) is chosen with consideration for both the aggressiveness of groundwater and the depth at which they are to be installed. Currently, drainage plastic pipes composed of the following materials are in high demand:

• PVC – polyvinyl chloride;
• HDPE – low pressure polyethylene;
• HDPE – high density polyethylene;
• PP – polypropylene.

The most common type of drains are plastic ones because they are the easiest to transport, install, and have all the parts needed for manufacturing readily available.

Thus, drains can be fully or partially perforated, and they are typically designed to be embedded no deeper than six meters. Couplers made of the same material are used to join pipes with each other. It is important for laborers to ensure that the water intake holes are situated on the drain’s sides when installing drainage pipes. The pipes’ upper and lower halves should be smooth and undamaged. The pipes are wrapped in geotextile to keep the holes from clogging. The layer of crushed stone that the drainage pipes are installed in is shielded from early siltation by the same material.

The proper slope of the drainage pipes is maintained when installing drainage around the foundation. This allows for a full-fledged water flow, preventing silting of the drains and erosion of the surrounding soil. It also considers the drained horizon’s water availability.

Primary components of the drainage system for walls

It is noteworthy that raising the longitudinal slope of drains above the minimum standards is not recommended because it adds to the volume of construction work that is required. The maximum permitted value of the water flow through the pipes, which is one meter per second, is used to calculate the maximum drainage slope.

To avoid water damage and preserve structural integrity, make sure your home’s foundation has adequate drainage. We have walked through the wall drainage process in this guide, emphasizing important steps that do-it-yourselfers should take.

First and foremost, it’s critical to comprehend the significance of drainage channels and how they help divert water away from the foundation. You can make a way for extra water to escape your house by digging around the foundation’s edge and setting up a drainage system.

Next, for a wall drainage project to be successful, choosing the appropriate supplies and equipment is crucial. The efficacy and durability of the drainage system are ensured by paying close attention to detail at this stage, from picking the right drainage pipes to choosing the right size gravel.

The drainage system’s functionality also depends on using proper installation techniques. This entails backfilling with gravel to offer stability and support, firmly positioning drainage pipes, and properly sloping the trenches to promote water flow.

Furthermore, maintaining the wall drainage system’s efficacy requires constant care. The lifespan of the drainage infrastructure can be extended by doing routine inspections, removing debris, and quickly addressing any damage or blockages.

In conclusion, even though wall drainage of the foundation may seem like a difficult undertaking, it is actually a doable do-it-yourself project with careful planning, close attention to detail, and adherence to the right techniques. You can prevent water damage and preserve the structural integrity of your home for many years to come by taking the required precautions to guarantee proper drainage.
