The Final Plan Details are Penned in. Almost Ready for Construction of the Vacation Home.

At a previous post, I discussed the materials to be used for the walls. We had the choice of regular cement blocks or bricks, the Convitek and later we were looking at Hebel and Aircrete.
Hebel and Aircrete are brand names companies in Mexico making a building material mixing cement, other materials and air. The production process created a building block which is lightweight, very tough when you hit it directly, yet soft enough to be able to be cut using a hand-saw. Installation time is very fast, using simple adhesive on all sides. The air pockets within the building block functions as a sound and thermal insulation system. This eliminates the need for additional installation of other materials for sound and thermal insulation. The building material is also able to withstand being in direct flame for four hours.
On a overall $250,000 to $400,000 building cost, the cost difference using Hebel/Aircrete vs regular cement block is estimated at $15,000. Taking into consideration the value and benefits it is a no-brainer and makes absolute sense to use Hebel or Aircrete.
We have also had some long meetings working on several building details. We have made 90% of the decisions for the number and locations of the electrical outlets and light switches. We have decided the route and functionality of the water supply piping, water storage and distribution, gas storage and distribution, gray water treatment.
Water and gas lines along with their respective controlling valves will be easily accessible for fast and easy access when there is a need for a repair.
The property has the appropriate surface inclinations so that the rain water can be collected and drained into the quite large cisterns. We are looking at one or two-cistern system with a range of 115 m3 to 180 m3 water storage facilities. This should provide us for quite a healthy safety large quantity of water supply in case of government water shortages
The stored water will be maintained and treated with chlorine and filtration both while stored in the cistern and with a whole house water filter before the water enters the house for consumption for shower or cooking.
Our engineer will be working in the coming weeks to create the project labor calendar and line up the builders. So everything is shaping up and is falling into place to be ready to break ground and start construction by the time the building permit is issued in about a month’s time from now.
Exciting times!!

New Thermal & Sound Insulating Building Materials for Selva Suites Home in San Pancho, Mexico.

We are still in search of the ideal material to build Selva Suites. In this earlier post, I discussed the Convitec material. While Convitec might be economical with some thermal and sound insulating properties, we are concerned about its stability, strength, and durability. I read in some forums of some people who had the unfortunate experience of mice or critters getting within the walls, under the stucco, eating away the material. In some cases, it was attributed to bad workmanship. However, what would be the long-term maintenance to keep this hermetically closed, so that critters do not get it? This is a concern.
An alternative that we are considering is a relatively new technology of synthetic cement blocks. These type of cement blocks were initially created by mixing concrete with ashes, creating air bubbles within the block. However, the challenge with this is that the recipe must be very accurate to produce a good and consistent-quality result. The technology evolved and new formulas which appear to be more stable producing a more consistent result. Every country and cement producing company markets the same material under a different brand name. In Mexico, there are two companies Aircrete and Hebel.
The material they sell has some amazing results and properties. The Aircrete and Hebel blocks are very light compared to regular cement blocks. It is easier and cheaper to transport. It appears to be easier and faster to install than regular cement blocks. Because of the air bubbles within the block, it provides extreme thermal and sound insulation. It is hard and solid, yet it can be cut easily even with a regular manual saw and it is extremely easy with an automated saw to cut through the lines for water and power. The installation videos available on YouTube appear simple. The material can withstand to be exposed to a continuous fire of four hours!!
We have requested more information and quotes from these companies. We hope the price is going to be appropriate for our budget and comparable to regular cement blocks.
