African Soil Stabilization for Mud Wall Rendering

In various part of world including Africa still mud wall is serving as building component. We, here, will discuss about African technologies to stabilize soil for protecting mud wall.

We will discuss about traditional materials more accurately natural materials as stabilizing agent. The materials have range from plant extract to cow dung. They are mixed with soil to render mud wall and purpose of treatment is to provide water resistance.

We will discuss about the country like Ghana, Upper Volta, Nigeria, Sudan and Ethiopia etc.

Cow dung treatment for mud wall
As stabilizer, an extract from boiled banana stems is mixed with soil. This technique is observed in the northern Ghana where lateritic soil is usually treated in this way.

Upper Volta
A varnish is provided to mud wall which is extracted from a plant local name is ‘am’. The present name of Republic of Volta is Burkina Faso. The country banks at upper part of Volta River which was colony of French community.


In northern part of Nigeria, extract collected form vine (Vitis pallida) used as stabilizer for water proof mud. The local name of the plant is dafara.

This is made of fruit pod from tree of lowest bean and serve as water proofing agent.

In Sudan mud houses known as ‘Jaloos’ are treated by water proofing materials produced locally from horse or cow dung. The local name of this is ‘Zibla’.

West Asia
Since biblical period, straw is using in this purposes with mud.

Straw is used to mix with soil paste having local name chika. They prefer straw of maize known as chid.

  1. Dear Colleagues,
    KALMATRON® KF-D is a Dust Controlling Binding Compound to control the air pollution by suppressing the Dust generated by ground roads, bulk handling, and transportation. KF-D is applicable an admixture of 8 3/4 Lbs or 4 Kg per 220 Lbs or 100 Kg cement respectively to Dust Control Material (DCM). DCM is applicable as a slurry poured dust emitted area.

    DIFFERENCE FROM KNOWN: require one time application instead of multiple sprays during of at 5 to 7 weeks.

    KALMATRON® KF-D designed as an admixture to the Cement’s Soils Containing Sealers of the CMS (Crumbled Material’s Sealant) for enhancement of soils consolidation with strength accelerating and any required level of liquid impermeability.

    KF-D performs as a compactor of crumbled concrete and densifier of disintegrated and/or soggy soils.

    KF-D provides stable consolidation of injected structures with increasing of compressive strength up to 40%.

    KF-D improves liquid impermeability of Earth-Material’s Structures (EMS) and concrete/masonry building’s elements.

    KF-D stabilizes the flowing of soggy soils of the fields, offshore, sinkholes, foundations, and etc.

    KF-D is a cost‐effective solution that utilizes unusable structures to be restored up to impermeable to the liquids without the need of isolating membranes or water mitigating solutions and devices.

    It is correct about high probability of rock fill particles rearrangement, but unfortunately there is no universal recipe because every time situation is different. Very often ground stabilization solves the problem by soil premix with additive and placement rock fill after

    For areas with active filtration or high water table, KF-D must be injected.
