Besides the costs for the actual foundation repair a homeowner is also confronted with additional costs for preparation and implementation of the recovery plan. The design value of the shear resistance is determined by the summation of the shear capacity of the prestressed masonry and additional shear reinforcement takes as: Problems with this type of foundation are mostly caused by wood decaying fungi, bacterial degradation or insufficient load capacity. Moreover, this part will provide guidance for the second part; concept development.

Then recesses in the floor are used to jack down the piles. So, as with most products, the higher the quality the more it will cost. And validation ensures that the design, as provided, fulfils its intended use. Sometimes the beams are connected fynderingsherstel cross beams.

Moreover the penetration of the pile decreases funderibgsherstel to greater pile-soil interface causing the pile to move down more difficult. The new foundation directly takes the loads after tensioning. Different concept designs will be developed through innovation one of which will be elaborated on in Part 3 — design validation.

Interesting fact is that the stiffer the floor is, the more counterbalance can be taken from the structure above. Demolition of wooden floor joists and subflooring of the whole ground floor. For high frequency driving a compressed air driven ram is placed on top of the pile. Maanen explained that if the funderingsherste still suffices Warenco in some occasions not only gives an enforcement period, but also the advice to e.


Needle beams in wall recesses transfer the loads from the bearing masonry wall via the prestressed concrete beam to the new piles. Then beams langshout are placed in funderingshershel longitudinal direction of the foundation. Followed by what cracks can tell about the settlement behaviour and how to investigate wooden pile foundations. The temperature at foundation level in the Netherlands will always be a bit lower but the other three components mentioned are abundantly available funderlngsherstel decay is facilitated.

This was done supplementary at the end of this thesis in order to underpin the performed hand calculations. This research was carried out in cooperation with the Dutch knowledge centre concerning foundation ahndboek KCAF which gave me the opportunity to apply the mostly theoretical education to an actual practical problem. This piling technique can be used for both small and large diameter piles.

Herewith, the axes used in this drawing correspond to the ones in the table. Hence it is likely to gain the most by searching for new innovative solutions for foundation repair. This will give an overview of the possible foundation repair methods available.

With this formula the contribution of the inner brackets is calculated with the use of the yield strength of shear reinforcement.


This makes it difficult, if not impossible, to for instance determine a square meter price per method. With this, lime is used as binder and sand as the aggregate. If the concrete floor is poured before piling it will give an additional load onto the old foundation which can lead to further damage and settlement.

Anchorages are used to stress the tendons.

The size of the bricks also differs per region and it was untilwhen the Housing Act Woningwet was introduced, that rules were set about the minimum exterior wall thickness. Foundation repair in time is necessary and can involve funderingsherstle use of a jacking system to provide adjustment for ongoing future settlements.


Foundations before were designed empirically without a Cone Penetration Test CPT or any geotechnical calculations. Different options to utilize the old structure are given. Next, an indicative action plan for the construction of the design is presented which will be used in the following paragraph to perform a rough cost estimate.

This, however, will probably not be feasible. Bottom driven tubular steel piles are most commonly used for foundation repair in the Netherlands. Thereafter funderingshersrel steel casing can be inserted, secured with grout, to include the weight of the foundation. It is also difficult, if not impossible, to get, for instance, provinces, municipalities or water boards Waterschappen liable for foundation problems because a plot owner is considered responsible for its own plot and these fundfringsherstel often simply lack the means to act.

As a conclusion of the above, three design principles are determined: Jack-down piles from a wall is only possible if the masonry is strong enough and if the building can provide enough reaction force by its own weight. Relatively small vibration free machinery is used funderringsherstel piling.

Most importantly; the design must be feasible and able to compete with existing construction methods. The first thing to do is to remove the existing floor first and prepare the site.


The heart distance between the piles is limited mainly because of arch action in the masonry. The water table must temporarily be lowered. The negative friction will, even when the point bearing capacity is exceeded, always cause significantly less settlement of the pile than the ground level.
