In the construction business the word "foundation" means building part taking all loads and transmitting them to the base. In this case, the base is ground. Recently a precast concrete foundation is widely used. Such constructions are placed around the whole structure perimeter, including each wall and outbuildings. It is mainly used in low-rise structures.

Special blocks and foundation cushion under them are made for this purpose. These blocks are both full-bodied and hollow. The first is made of rubble concrete. The second one is made in production, mainly of conventional concrete, but sometimes - silicate. Reinforced concrete is also a common material for the production of blocks.

Pros and cons of precast concrete foundations

Advantages list:

Quick assembly design. Just a couple of hours after the end of installation work you may begin the wall construction. It is not needed to wait for a month or more, as in the case of using a monolithic base; A...

House Foundation Types

A house needs a foundation to shoulder its considerable weight, provide a flat and level base for construction and separate wood-based materials from contact with the ground, which would otherwise cause rot and allow termite infestation.

Depending on when and where a house was built, the foundation may be made of stone, brick, preservative-treated lumber, concrete block, or poured concrete. By far the most common material for foundations is concrete. Most houses have a raised perimeter foundation that supports floors and load-bearing walls. Some are built on a flat, concrete slab that provides both a base for the structure and the bottom floor of the house. Still others, notably vacation homes or small, older houses, rest on a series of concrete piers.

Some houses utilize all of these methods for different portions of the house. Houses with perimeter foundations, for example, often have post-and-pier supports...

What salesmen of aerated concrete are silent about?

Production of cellular concrete is currently experiencing a rebirth. Volumes of production are increasing, the market is growing. And it's all thanks to the new rules introduced by the thermal resistance of building structures prescribed in SNIP II- 3 -79 *, by which through the efforts of advertising campaigns was claimed by one of the main positive features of aerated concrete - good thermal resistance of the material. Managers of manufacturing companies, promoting the product, goods touted talent eastern market. But is it as good as it is told in advertisements? What is kept under wrap?

Cellular concrete - artificial stone with evenly distributed pores. Derived of cellular concrete are foam concrete, aerated concrete. The difference between these materials is determined by the technology of production of these materials.

Foam concrete - light cellular concrete, the result of curing of a solution...

How to make a foundation for a house with his own hands

Building a house is a fairlya complex, time-consuming and responsible process. The process of construction of a residential building involves several stages, one of which is mounted to the foundation of the house. This stage is one of the key as well as the quality of laying the foundation determines the durability of construction, the protection of it from a variety of internal and external factors, the degree of security. Competent approach to the device foundation to avoid many mistakes. In addition, it should take into account the fact that the experts distinguish several types of foundations, each of which has its own characteristics and is suitable for a particular soil type structure. Depending on the design features adopted to allocate tape, pile, slab and pier foundation. And now - a little bit about each of them.

I think some people are missing the point. The thermal mass works as a heat sink, absorbing heat during the day, releasing it at night. And it works during the summer and winter. So the R-value isn't the point. So yes, a good deal of thermal mass there.

I'm no expert. Just fundamental knowledge, so do some more research. If you just fill it with sand, it is a passive system and therefore won't radiate much to the rest of the house. You may want to look at an active system in conjunction with thermal mass. It would consist of hot water heating, the thermal mass would supplement the heating of a boiler. Then you could build on a slab and use radiant floor heating. You have a range of possibilities. For example, you could build a trombe wall. It is an interior masonry wall and acts like a heat sink. It requires special consideration of your region, but so do all solar homes. You need to know the latitude and do some trigonometry to determine the best orientation for sun angle, soffit...

Here at, we regularly receive questions from readers about the best way to insulate a basement wall. Since these questions pop up frequently, it’s time to pull together as much information as possible on this topic.

In this article, I’ll try to explain everything you always wanted to know about insulating basement walls.

Is it worth insulating a basement wall?

If you live in Climate Zone 3 or anywhere colder, it’s cost-effective and wise to install basement wall insulation. This advice applies to those who live in most of New Mexico and most of Alabama, as well as all of Oklahoma, Arkansas, and South Carolina, and anywhere colder than these states. (Click here to see a climate zone map.)

Canadian researchers who studied basement insulation methods and costs in five Canadian locations (Toronto, Ottawa, Halifax, Edmonton and Victoria) concluded that “for all types and sizes of basements assessed in this study, the lowest total...

SITE DRAINAGE should be kept separate from gutter runoff or the drain pipes can become overloaded and flood.

Roof gutters, curtain drains, and slope are key

There are two things to think about in keeping a site dry: water coming off the roof; and rain soaking into everything else that's at site level or higher. Consequently there are two drainage systems — one for gutters, and one to keep the immediate area clear.

In small yards or those that are not configured for a rain garden or drywell, getting gutter runoff "to daylight" is an absolute minimum. This means that gutter drainpipes are terminated above-ground to let them empty above ground. Many local codes specify at least five feet away from the house without also specifying "and downhill."

Avoid runoff in the streets, recharge the ground water
As land gets developed, rainfall is increasingly diverted from ground storage and directed to storm drains. This further depletes...

This article explains how an old house might have dealt with rain and dampness when it was first built, what could have happened since to change that and ways of reinstating the original balance.

If the fabric of an old building allows water vapour to enter but dry out again, this is called 'breathing' and means that damp can dry out harmlessly.

If water is trapped inside the walls of an old house by impervious materials or finishes it can cause decay.

A genuinely old building usually relies upon this 'breathing' but when the pores and surfaces that permit this to take place have been sealed up then problems can occur.

1 How old houses cope with rain

This section explains how traditional roofing and external wall materials worked.

The original builders of old houses had little in the way of genuinely waterproof materials which were both cheap and readily...
