Technology for tomorrow (T4t)

Manufacturing/Building Method

ISSB Granaries are individually constructed with the use of a block press to produce Interlocking Stabilized Soil Blocks

Intellectural Property Type

Trade Secret

User Provision Model

The ISSB granary cannot be purchased as a product. The construction process is taught to the farmers so they can build it themselves. ^Interview ^with ^inventor

Distributions to Date Status

There are 30 units constructed to date in Uganda. ^Interview ^with ^inventor

Design Specifications

Design specifications: ^Interview ^{with representative}

The construction of the ISSB Granary requires Interlocking Stabilised Soil Blocks (ISSB) produced via a block press.
Blocks are made on the site thereby reducing transportation costs.

Technical Support

Trained village level entrepreneur/manufacturer provide support.

Replacement Components

The granaries are constructed locally on site. The only replacement parts are the bricks.

Lifecycle

Managed at household levels and can last many years. ^Interview ^{with representative}

Manufacturer Specified Performance Parameters

The granaries have demonstrated the capacity to store maize grain free from pests for a period of more than 6 months reducing post harvest waste and ensuring better prices for farmers.
In comparison to the traditional granaries, the construction of the ISSB Granary requires minimum skills and uses only environmentally friendly technologies

Vetted Performance Status

The interlocking stabilized soil blocks perform better than clay bricks by increasing the structural stability of built walls, while reducing the amount of cement needed as mortar.

Safety

No known hazards.

Complementary Technical Systems

T4T also offers a variety of products such as Makapads, Incinerators, ISSB water tanks, thin shell concrete roofs and more.
